This is the sort of thing I would have posted about on the obsolete computer museum helpline back in the day (R.I.P. OCM Helpline), like the time I was surfing using "bobcat" on a Compaq Plus, or the time I was running lynx in a shell account via a terminal program on an Apple IIGS.
I have this Pentium 166 laptop which the HDD died in recently, so I put in a 2GB flash card and put Windows NT 4 on it just for the heck of it, since I had never used it before. It seems like a lot of programs that run in 9x or 2000 will also run in NT4. It has a lighter memory/disk footprint than 2000, but Direct3D, power management, plug&play, FAT32, and USB support are all missing. Nice OS, I guess, although I never would have used it in the 90`s because I relied on more DOS programs at that time and many of the Windows programs I use now didn`t exist yet.
Now I`m fooling with NT 3.51, which is a similar OS but with the retro 3.x style interface. The drivers for my old PCMCIA 802.11b wireless card weren`t happy in 3.51, so I resorted to a serial link to my other laptop. Thanks to tips from this page I was able to get online with Firefox 2:

I`m going to take this to work and sit and read slashdot, see how many people walk by and do a double take...
